May be interfered with and removed from the surface of the grill 670. Since the user does not have to directly remove the dust or the like stuck on the surface of the grill 670, the cleaning of the cyclone dust collector 61 is easy and hygienic.

Hereinafter, the operation of the vacuum cleaner according to an embodiment of the present invention will be described.

When the fan motor (not shown) of the main body 10 is driven, air on the surface to be cleaned may be sucked through the suction part 62 by the suction force of the fan motor (not shown). The sucked air may sequentially pass through the extension tube 63, the handle tube 64, and the flexible hose 66, and may be introduced into the cyclone dust collector 61 mounted on the main body 60.

Air introduced into the cyclone dust collector 61 is guided to the cyclone chamber 614 through the inlet portion 612. Air guided to the cyclone chamber 614 rises while turning along the outer circumferential surface of the grill 670.

Dust that is heavier than air may be dispersed radially outward by centrifugal force and introduced into the dust collection chamber 615 through an opening 615a located at the top of the cyclone chamber 614. Dust introduced into the dust collection chamber 615 may be collected by the dust collection chamber 615 while falling by gravity.

In the cyclone chamber 614, the air from which dust is first removed by centrifugal force may pass through the air passage hole 672 to filter out dust of a predetermined size or more. The air passing through the air passage hole 672 may be guided upward through the outlet portion 614a. Air guided to the middle cover 611a through the outlet part 614a may be filtered fine dust by the fine filter 68 provided in the middle cover 611a.

Finally, the clean air exits the cyclone dust collector 61 through the outlet 613 of the upper cover 611 and exits to the outside of the main body 10 through a fan motor chamber (not shown). An outlet 613 side of the upper cover 611 may further include a filter (not shown) for filtering dust in the air exiting the outlet 613.

Referring to FIG. 4, the grill assembly 67 provided in the cyclone dust collector 61 according to an embodiment may be detachably mounted.
